But I tell you that men will have to give account on the day of judgment for every careless word they have spoken.Matthew12:36

"If your brother sins against you, go and show him his fault, just between the two of you. If he listens to you, you have won your brother over.But if he will not listen, take one or two others along, so that 'every matter may be established by the testimony of two or three witnesses.'If he refuses to listen to them, tell it to the church; and if he refuses to listen even to the church, treat him as you would a pagan or a tax collector.Matthew18:15-17

All of them were filled with the Holy Spirit and began to speak in other tongues as the Spirit enabled them.Now there were staying in Jerusalem God-fearing Jews from every nation under heaven.When they heard this sound, a crowd came together in bewilderment, because each one heard them speaking in his own language.Utterly amazed, they asked: "Are not all these men who are speaking Galileans?Then how is it that each of us hears them in his own native language?Acts2:4-8

So it is with you. Unless you speak intelligible words with your tongue, how will anyone know what you are saying? You will just be speaking into the air.Undoubtedly there are all sorts of languages in the world, yet none of them is without meaning.If then I do not grasp the meaning of what someone is saying, I am a foreigner to the speaker, and he is a foreigner to me.So it is with you. Since you are eager to have spiritual gifts, try to excel in gifts that build up the church.For this reason anyone who speaks in a tongue should pray that he may interpret what he says.1 Corinthians14:9-13

I thank God that I speak in tongues more than all of you.But in the church I would rather speak five intelligible words to instruct others than ten thousand words in a tongue.1 Corinthians14:18-19

Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up according to their needs, that it may benefit those who listen.Ephesians4:29

Above all, my brothers, do not swear,not by heaven or by earth or by anything else. Let your "Yes" be yes, and your "No," no, or you will be condemned.The Prayer of FaithJames5:12
